This paper treats the industrial application of computer-algebra simulation (CALS). CALS is a combination of symbolic and numeric methods, which is very well suited for efficient solving of complex problems. Because it is an innovative "hybrid" technique, completely new ways open up for approaching practical problems. The basis of CALS are mathematical models reproducing reality in sufficient detail, so that CALS is independent of any specific field. Based on Mathematica, it is outlined how this method can be brought to bear on real-life problems. (0 References).
